Object PATCH for efficient Swift based Cloud-Sync services

Registered by Ben Lapid on 2013-05-19

An attempt to allow Swift to host efficient cloud-sync services (similar to Dropbox and others). Currently, an attempt to implement such services will result in a waste of bandwidth when objects are changed. This happens because on each change, the entire object has to be re-uploaded. Therefore, implementing a "PATCH" method for objects, allows us to send only the change and not the entire file, saving precious bandwidth.
In addition, we can throw in a FUSE based client as a proof of concept. Combining the two, one can "mount" a Swift container onto the filesystem and any user-land application can work with those objects as if they were normal files.
